The girl and the 40kg dog have a treehouse! To get into the treehouse, the girl uses a winch to raise the dog elevator and then climbs up herself, The elevator is initially at rest on the ground. If the girl can raise the elevator at 0.3 [m/s) after 5 seconds, use the EQUATION OF IMPULSE AND MOMENTUM to find the tensile force in the cable she can impart by turning the winch. You may assume frictionless pulleys and that her force is constant Z
